A fix for this issue has been included in the latest python-dns update in
Ubuntu Linux.  See
https://launchpad.net/ubuntu/+source/python-dns/2.3.0-5.1ubuntu2 for
details.

Bug #863364 in the patches section has a different approach to fixing this
same problem.

Ok I can't seem to attach the file so you will have to manually edit
win32dns.py.

look for this chunk of code:
                try:
                   
nameserver,dummytype=_winreg.QueryValueEx(z,'NameServer')
                    if nameserver and not (nameserver in nameservers):
                        nameservers.extend(stringdisplay(nameserver))
                except EnvironmentError:
                    pass

(starts around line 94)

....immediately after that "try/except" block, paste this code...
                try:
                   
nameserver,dummytype=_winreg.QueryValueEx(z,'DhcpNameServer')
                    if nameserver and not (nameserver in nameservers):
                        nameservers.extend(stringdisplay(nameserver))
                except EnvironmentError:
                    pass

see the only difference is that now instead of only checking for
"NameServer" it will check for "DhcpNameServer" as well.

hope that helps someone :)

I am on Win XP Pro, and have the same problem.  I looked into the
win32dns.py source code and found that it looks into the windows registry
for the "NameServer" key.  However, in my case the value for NameServer is
empty.  However, I do have an entry under DhcpNameServer, so I added 6
lines of code to win32dns.py to check both NameServer and DhcpNameServer
for values.

I will try to attach the updated win32dns.py file.
